Imijikelezo yenkxaso yokondla inzwa ifakiwe, kwaye umlinganiso yi-ratiometric-inqanaba lesibini elinokucwangciswa lokufumana inzuzo inokukhulisa ii-sensors ukusuka kwi-1mV / V ukuya kuthi ga kwi-500mV / V (500Ω ukuya ku-60kΩ).
Umthombo wangoku we-chip uvumela ii-sensors kubandakanya i-Pt100 ukumelana kweplatinam kunye ne-diode yohlobo lwe-thermometer ukuba ifundwe, kwaye kufakwe inzwa yeqondo lobushushu kwi-chip.
Iziphumo zinokubakho nge-SPI (10MHz), mna2C (esemgangathweni, ekhawulezayo kunye nesantya esiphezulu) okanye a2Ifomathi yocingo olunye eyenziwe ngu-C eyi-100kHz ebizwa ngegama elithi 'OWI' nguRenesas.
Idatha ye-OWI inokuthunyelwa umva nge-4mA ukuya kwi-20mA yangoku-loop ebaleka naphi na phakathi kwe-7V kunye ne-48V isebenzisa umtshintshi wangaphandle we-npn. Ukusebenza nge-JFT yangaphandle, isekethe yangaphakathi inikezelwa ukufumana uloliwe wamandla we-5V we-chip kwi-loop yangoku.
Kukwakho nesiphumo se-analogue-esingaveli ngokuthe ngqo kumqondiso wokufaka, kodwa kwimveliso yedijithali yenkqubo yokulungisa eyakhiwe ngokutsha nge-16bit ADC. I-Absolute (0 -10V) kunye ne-voltage ye -ometometric, i-loop yangoku, okanye ukuphazamisa iziphumo ze-analogue ziyaxhaswa.
Ukusebenza kwe-Chip yenye yeendlela ezintathu ezisisiseko
Imodi yokulala icetyiswa ukuba inzwa kunye nemveliso yedijithali. Isimo sokungenzi nto singeniswa ngokuzenzekelayo emva komyalelo wokwenza ubuncinci bokusetyenziswa okwangoku, ngelixa ujongano luhlala luphulaphule ukwamkela imiyalelo.
Iyavuka emva kokufumana umyalelo osemthethweni, iphumeze, ibonelele iziphumo kunxibelelwano lwedijithali, kwaye ibuyele kokungenzi nto emva kokulanda idatha. Ukuphinda kulandwe kwedatha akuxhaswanga, kwaye akukho analogue outpt.
Imowudi yolawulo yeyona ilungileyo kuvavanyo, kuvavanyo, nakwimilinganiselo. Yonke imiyalelo iyafumaneka, zombini iziphumo zedijithali kunye neze-analog ziyaxhaswa, kwaye yonke imisebenzi iyafumaneka. Ukuvela kwakhona kunye nokuqhubeka kokudibana kwedijithali kuyafumaneka.
Imowudi ye-cyclic iyazimela, kwaye imilinganiselo yesenzi iphindaphindwe ngokuzenzekelayo kwaye iqhutyelwa kuhlaziyo lwemveliso (yedijithali okanye ye-analogue okanye zombini). Le ndlela iyacetyiswa kwizicelo zemveliso ye-analog. Inqanaba lokulinganisa (kungoko inqanaba lokuhlaziywa kwemveliso) linokuqwalaselwa.
Umsebenzi ungaphezulu kwe-2.7V ukuya kwi-5.5V (7V ukuya kwi-48V nge-JFET yangaphandle) kunye -40 ° C ukuya kwi-125 ° C.
Ukupakisha kukufa-on-wafer okanye i-4 x 4mm QFN eneendawo ezinamanzi zokuhlola ukuhamba kwakhona.
Izicelo zibonwa kwangaphambili kuxinzelelo, ukuhamba, kunye nenqanaba lokuqonda, inkqubo yokuzenzekelayo, umatshini wefektri, iimpahla ezimhlophe, imeko yomoya, izikali ezinobunzima, ukujonga uxinzelelo lwegazi kunye nokujonga impilo
